OK, big mistake you made to come in this forum, as you get answers...
Here inland my wind is flaky at best, so I use an old longboard for outings up to about 11-12 knots. Here are gybing clips - sort of. Probably most of it is about how
not to do it, but whatever.
Forewarning: I think it's gay to pay attention to what other men wear -there, I said it

. Having said that, note the booties for riding the rail, the torn sails, and the strong harness lines.

Clip 2 - I reckon clew-first (sail backwards) gybes are more natural than normal gybes, whether longboard or on the 105l board and planing. Not sure why, but if you're comfy at riding clew-first, try it.
Clip 3 - a bit fancier, as I'm facing the wind into the gybe. Note this can be done equally on a 100l board, will try to find clips of this move on my Exocet.
Clip 4 - OK, nothing to do with gybing - just a party trick.
